This focuser aims to solve a couple of problems: 1. Aside from the motor, it needs no parts (belts, gear, etc) 2. It stays fixed to the lens (not unique, but useful) 3. The gear design increases contact patch, reducing backlash 4.…
As a beginner, it was difficult for me to work with a self-printed focuser. I therefore designed an adapter for a Crayford 1.25 inch focuser, which can be bought on Aliexpress or Amazon. The adapter can be installed instead of the…
